om Boisins Nn UNDEBFRAME.

Be it known that I, ALLEN E. OSTMND, a .citizen of thevUnited States, residing at Paterson', New Jersey, have invented a certain new and Auseful Ir'nl'irovementv in Car' Bolsters and Un'de'rframes, of which the followin is a full, clear, and exact descri tion, suc 1 as will enable others skilled in-t e art to which it appertains to makeand use the same, reference being had'to the accompanying drawings, formingpart of this specication, in which-'- Figure 1 is-a side elevational view of abolster constructedin accordance with -my invention; Fig. 2 is a bottomA` plan view of the bolster and a portion of the undeifiame Fig. 3 is a sectional view take'n on the line 3.-3 ofFig. 1 Fig. 4 is a view similar to Fig.

2 with the bottom cover plate of the bolsterI removed; and Figs. `5 and 6 are sectional views taken on thelines 5'- 5 and 6-6, respectively, of Fig. 3.

This invention relates to car underframes and vparticularly to the construction of-'the ame.

The main object of my invention is to probolster of an underfr vide a built-up bolsterl which is strong andf light, and which is so designed that the arts thereof i can be assembled and rivete tcgether before the bolster is'placed in operative o sition.

Re erring to the ldrawings which represent the preferred form of my invention, 1 desig.

nates flanged diaphragme preferably formed of pressed metal, and arranged between' the center sills and the side sills of the car.- The bolster .comprises four of these diaphragme 1 avanged 1n pairs, as shown in Fig. 2, and.

with their iianges projecting o posit'e directions. The diaphragme of 4eac vpair 'are spaced apart to provide openings be` tween their vertical webs' to 'receive the member 'which ties the pairs ofdia}1 hrag-:r:ns

together. This member preferab sists of a casting 2 provided with an projecting wedge-shaped wings or Iins 4l that are interposed between the pairs .of dia.

of a plate'g that extends from side sill to side sill and is secured to the upper iianges of the diaphragme 1 by rivets 10.- This tension plate 9 is not secured to the diaphragme, however, until after the bolster has been' placed in position and the center sills have been let down into the bolster and secured thereto.

llVithv a construction of this description I am able to usea machine riveter for driving the rivets 5 and 7, which'connect the compression member 2 and diaphragmeA 1v together, vand.- after these parts have been assembled I 'arrange-them 1n position and then place the center sills in pairs of diaphragms. f

The center sills which I preferto use do not end sill and the' bolster and are spliced to erably formed of pressed metal andare c annel-shaped in cross section, and the center sills 12 are 4also formed frompressed metal, .each Aof said center sills com rlsing a vertical wel rovidedat its upper edge with an integra. angle 14.Y Ihe angle 14 does not extend the entire length of' the vertical web of the center sill'but terminates at thebolster so that the portion of the centei sill which projects beyond the bolster has no lower flange.
